SPECIFICATION forming part of Letters Patent No. 561,894, dated June 9,1896.

Application led October l2, 1895. Serial Noi 565,524- (No model.)

To @ZZ wwm, it may concern:

Be it known that 1, THOMAS R. JORDAN, a subject of the Queen of England,and a resident of New York, in the ccuntyof New York and State of NewYork, have invented certain new and useful Improvements inSafety-Envclops, of which the following' is a speciiication, referencebeing had to the accompanying drawings, forniin a part thereof, in whichm similar letters of reference indicate correspon ding parts.

My invention relates to improvements in safety-envelope, and the objectthereof is to provide an envelop or cover from which the contents cannotbe extracted Without leaving distinct evidence upon the envelop or coverthat the saine has been tampered with.

lilith this and other objects in view I construct my improved envelop orcover as de 2o scribed in the following specification and illustratec'lin the accompanying drawings, in Which- Figure l is a blank from whichmy improved envelop is formed. Fig. 2 shows the same folded. Fig. 3 is amodiiication of the blank shown in Fig. l. Fig. i is a sectional vieivof the saine. Fig. 5 shows the contents secured Within the envelop andthe blank open 5 and Fig. G illustrates the inode of inserting 3o thecontents Within the envelop, the same being sealed.

In the practice of my invention l provide a blank, as shown in Fig. l,consisting of the main or body portion B, provided Withlateralextensions or side flaps O, which are guinmed upon the outer edgesthereof, and the end extensions or flaps- D E.

At the intersection of the extension or flap E and the main or bodyportion B is formed a transverse opening F, and at the intersection ofthe lower extension D and said body portion is secured a tongue or stripG, provided on the lower portions thereof with slits or incisions g, asshown in Fig. l, and said tongue is adapted to pass through said openingF upon the outside of the envelop.

informing the envelop or cover the end flap E is first folded inwardlyupon the inain or body portion 13. The side iiaps C are then 5o foldedupon the flap E and secured in position by means of the glue or otheradhesive substance upon the outeredgesthereof, after which the flap D isfolded inwardly upon said flap C and secured thereto by means of theglue or adhesive substance upon the outer 5 5 edges thereof, therebyforming the envelop or cover, as shown in Fig. i).

The letter or matter to be sent in the envelop is then provided with aslit or incision, into which is inserted the end of the tongue 6o G, andthe letter is then rolled about said tongue sufficiently to pass throughthe opening F into the envelop, and the incision in the latter engagesthe slit g upon the edges of the'tongue G and secures saidletterwithin65 the envelop.

Figs. 3 and d illustrate a modification of my improved envelop, relatingparticularly to the opening in the extension D2, and this extension ishere shown provided ivith a re- 7o ceding inouth having a transverseslit f' to receive the tongue and through which the contents of theenvelop is adapted to be inserted. The construction Vis similar to thatshown in Fig. l. By securing the letter or other article to the tongueor strip Within the envelop any effort to Withdraw the same from theenvelop will at once detach the tongue or strip from the envelop andclearly show that the same has been tampered with.

Various changes and alterations may be ina-de in the construction of theseveral parts Without departing from the spirit and scope of theinvention.

The niain and essential features of the construction are the smallopenings in the upper portion of the envelop or cover, through which theletter or contents of the envelop is adapted to be inserted andthetongue or strip secured within the saine. 9o

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

l. An envelop or cover for letters or other articles, provided with asmall transverse opening in. the top thereof, and having an independenttongue or strip projecting through said opening, over which the letteris adapted to be rolled and inserted tl'lrough the opening into theenvelop.

2. An envelop or cover for letters or other articles provided with asmall openin g, having IOO a tongue or strip secured upon the insidethereof, adapted to engage a letter or other article, and retain thesznne Within the envelop, whereby the contents cannot be WithdrawnWithout damage to the envelop.

3. An envelop or cover for letters or other articles, provided with itsmall openingin the top thereof, and having secured upon the inside ofthe same t tongue or projection, eX- tending through said opening, saidtongue bein g provided upon the lower portion thereof with obliqueincisions or slits, adapted to engege it puncture in the contents of theenvelop, and retain the same Within the envelop.

l. An envelop or cover for letters or other articles, having :t smallopening formed at the juncture of the mitin or body portion and theupper flap, which opening is unelosed when the flap is folded and theenvelop is sealed, and a tongue or projection secured within the envelopand extending outwardly through seid opening in the top thereof, saidtongue having slits or projections upon the lower portion thereof,adapted to engage a puncture in the contents of the envelop, which isadapted to be rolled around the tongue and inserted through said snmllopening after the envelop has been sealed.

In testimony that I claim the foregoing` as my invention I have signedmy 11a-nie, in presence of the subscribing Witnesses, this 5th day ofOctober, 1895.
